HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 657, 873, 661, 613 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 657, 873, 661, 613 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 657, 873, 661, 613 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 657, 873, 661, 613 is 1.
HCF(657, 873, 661, 613) = 1
HCF of 657, 873, 661, 613 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 657, 873, 661, 613 is 1.
Highest Common Factor of 657,873,661,613 is 1
Step 1: Since 873 > 657, we apply the division lemma to 873 and 657, to get
873 = 657 x 1 + 216
Step 2: Since the reminder 657 ≠ 0, we apply division lemma to 216 and 657, to get
657 = 216 x 3 + 9
Step 3: We consider the new divisor 216 and the new remainder 9, and apply the division lemma to get
216 = 9 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 657 and 873 is 9
Notice that 9 = HCF(216,9) = HCF(657,216) = HCF(873,657) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 661 > 9, we apply the division lemma to 661 and 9, to get
661 = 9 x 73 + 4
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 4 and 9, to get
9 = 4 x 2 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9 and 661 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(661,9) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 613 > 1, we apply the division lemma to 613 and 1, to get
613 = 1 x 613 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 613 is 1
Notice that 1 = HCF(613,1) .
